Arched windows are an impressive architectural feature that adds sophistication to your window, but may also let in undesired light and glare. Our stationary arched window shades are exactly what you're looking for and will gently filter or block light through an insulating cellular shade. To order an arched window treatment online, the height of your window must be exactly half of the width. This is called a perfect arch. If your arched window is not a perfect half circle, you need to make a template of your window - please contact our customer care team for detailed instructions. Ordering a custom arched window treatment online ensures a perfect fit for your perfect arch.
